Western blots were performed as previously described[11 (link)]. The following reagents were used: rabbit polyclonal antibody to cyclooxygenase-2 (COX-2) (AbcamInc, Cambridge, MA, United States), glutamate-cysteine ligase modifier subunit (GCLM) (AbcamInc, Cambridge, MA, United States), inducible nitric oxide (NO) synthase (iNOS) (Santa Cruz Biotechnology, Santa Cruz, CA, United States), endothelial NO synthase (eNOS) (Santa Cruz Biotechnology, Santa Cruz, CA, United States), glutamate-cysteine ligase catalytic subunit (GCLC) (AbcamInc, Cambridge, MA), glutathione (GSH) peroxidase (GPx) (AbcamInc, Cambridge, MA, United States), heme oxygenase-1 (HO-1) (AbcamInc, Cambridge, MA, United States), superoxide dismutase (SOD) (Santa Cruz Biotechnology, Santa Cruz, CA, United States), glyceraldehyde-3-phosphate dehydrogenase (GADPH) (Cell Signaling, Danvers, MA, United States), rabbit monoclonal antibody to NF-κB (Cell Signaling, Danvers, MA, United States), catalase (CAT) (Rockland Immunochemicals, Limerick, PA, United States), and mouse monoclonal antibody to nicotinamide adenine dinucleotide phosphate (NAD(P)H) quinone oxidoreductase-1 (NQO-1) (AbcamInc, Cambridge, MA, United States) followed by secondary anti-rabbit or mouse immunoglobulin G (Cell Signaling, Danvers, MA, United States).
